I'm trying to load inception_resnet_v2_2016_08_30.ckpt file and do testing.
The code works well with single image (entering oneFile() function only once).
If I call oneFile() function twice, the following error occur:
ValueError: Variable InceptionResnetV2/Conv2d_1a_3x3/weights already exists, disallowed. Did you mean to set reuse=True in VarScope? Originally defined at:
I found related solution on Sharing Variables
If tf.variable_scope meet the same problem, could call scope.reuse_variables() to resolve this problem.
But I can't find the slim.arg_scope version to reuse the scope.
